At the end of
"The Vampire Diaries" Season 3, Mystic Falls lost its favorite witch, Bonnie. But she's not gone for good -- check out this interview with
Kat Graham at the 2013 San Diego Comic-Con for information on Bonnie's life after death.

"The only one who can see her on the Other Side is Jeremy, and that's where the season takes off," Graham said of her "TVD" state at the beginning of Season 5.

Alas, it sounds like being a ghost is a frustrating experience, even for a powerful witch like Bonnie. "They can still come into the human dimension," she explained. "But only someone like Jeremy can see [them]."

How will Bonnie take her death? And how does she keep her friends from finding out what has happened for so long? That will have to wait until "The Vampire Diaries" Season 5 premieres this fall.
